Neutral mystic On Aug 30, 2001, mystic from Ewing, KY (Zone 6a) wrote:

An erect, many-branched, herbaceous perennial that grows 2-3' tall and has narrow, almost needle-like leaves and profuse clusters of small, white flowers which bloom in mid to late summer. All parts of the plant have a strong, mint-like aroma. Not invasive like other mints.
